Depending on the way they go, they could have the Chucky Puppets more in "key" moments, while the rest are possessed people by that of the Cult/Army (and Tiffany vibing) from the TV show.
NiChucky, Tiffany, G&G, and the Counselor come to mind. Heck that number could vary depending on the scenario that they have written, depending on if it's a traditional adaptation of the show or something more like an Original-IP, where you could actually loosen and allow for more Possessed peoples.
